Answer» NaCl(Table Salt) is soluble in water.Reaction:NaCl(solid) + H2O -> Na+(aqueous) + Cl-(aqueous) + H2O Explanation:On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens\' side of the water molecule. Color scheme: Red(Oxygen) Blue(Hydrogen)This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms. A hydration shell is formed around them which prevents Na+ and Cl- to form ionic bonds. A colour less solution is formed consist of strongly alkalic sodium hydroxide and hydrogen gas |

The coronary arteries branch off the ascending aorta to supply the heart with blood.• The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.• The descending thoracic aorta travels down through the chest. Its small branches supply blood to the ribs and some chest structures.• The abdominal aorta begins at the diaphragm, splitting to become the paired iliac arteries in the lower abdomen. Most of the major organs receive blood from branches of the abdominal aorta. |
